Sclerotiniaceae
Facesoffungi number: FoF 05953
Taxa are saprobic or plant parasitic. Ascomata are apothecial. Apothecia are cupulate to plane or pileate, stipitate and usually emerge from sclerotia. The ectal excipulum is composed of cells ofmtextura globulosa or textura prismatica and medullary excipulum is composed of cells of textura prismatica, textura intricata or loosely arranged hyphae. Paraphyses are filiform, cylindrical and hyaline. Asci are 2–8-spored, amyloid, rarely non-amyloid and sometimes arising from croziers. Ascospores are ellipsoid, rarely fusoid or allantoid, smooth, hyaline, rarely warted, guttulate, often with sheath, 1–3-septate and form microconidia by budding (Saito & Kaji 2006, Fuhrer & May 1993, Beaton & Weste 1984, Hosoya et al. 2014, Salgado-Salazar et al. 2018, Andrew et al. 2012, Batra 1991, Holst-Jensen et al. 1997, Hustad & Miller 2011, Kohn & Nagasawa 1984, Schumacher & Holst-Jensen 1997, Schumacher & Kohn 1985, Spooner 1987, Verkley 1993, Livsey & Minter 1994). Asexual morphs are hyphomycetous, acervular or pycnidial. Conidiogenesis is holoblastic and phialidic. Conidia are aseptate hyaline, rod-shape and smooth (Jaklitsch et al. 2016, Livsey & Minter 1994).
Notes – This family includes plant parasites and phylogenetically formed a monophyletic clade sister to Rutstroemiaceae. Some taxa are pathogens on various mono and dicots stems, leaves, flowers, fruits, seeds and wood, which cause stem cankers, flower blight and fruit and leaf spots (Navaud et al. 2018). This family also includes mould pathogens such as the grey mould pathogen Botrytis cinerea, which consider as one of the ten most devastating plant pathogens (Dean et al. 2012).
